TBMB Claims Structural Analysis: Upper Swift River Geology

The Yukon's upper Swift River area contains stratiform zinc occurrences. A structural analysis of the TBMB claim group reveals east-southeast-trending folds controlling rock distribution and defines a general stratigraphy with three siliciclastic units and two intervening base-metal-sulphide-bearing strata. The dataset was published by the Government of Yukon and last updated in April 2026.

Use Cases

• Modeling stratigraphy based on defined lower, intermediate, and upper siliciclastic units.
• Analyzing fold-controlled mineral distribution based on described east-southeast-trending F1 anticlines and synclines.
• Comparing structural linkages between claim areas based on similarity of rock types.
• Mapping base-metal-sulphide-bearing strata based on described intervening volcanic and marble units.

Strengths

• Analysis defines a general stratigraphy with three distinct siliciclastic units.
• Description includes specific structural features like east-southeast-trending, km-scale F1 folds.
• Dataset is associated with a specific geographic area (upper Swift River, Yukon) and claim group (TBMB).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to open_canada.
